Patent KR-890002193-B1 (KR)
Title: Transmitter of vehicle information
Inventor: OZAI HAZIME
IPC: H04L1/22
Filed: 1985-01-17
Granted: 1989-06-22
Abstract: A predetermined signal is added in succession to information which is sent from a transmitting portion.  A receiving portion which has received the information compares the information and the signal succeeding to detect an error rate and produces a predetermined value.  A measure can be thus taken before the loss of the function of a transmission line is clarified.

Granted: 1990-04-28
Abstract: Coaling apparatus for strip metal comprises a series of spaced cooling rolls which provide a serpentine path for the strip, a cooling roll, temperature sensors for detecting the temperature across the strip, and a strip temperature control and device.  The gas jets are provided with gas flow control valves which are electrically connected to the control and arithmetic device.  The temperature sensors are also connected to the control and arithmetic device.  The metal strip is cooled by directing cooling gas onto the strip as it passes around a series of rollers, e.g. in a continuous annealing line or a galvanizing line.

Abstract: The appts. includes an ignition signal generator, an ignition circuit, an ignition-noise masking signal generator, a switching transistor and an ignition coil. The ignition signal of the gererator is supplied to the ignition circuit to produce a first igniton pulse and a second ignition pulse which is electrically isolated from the first ignition pulse. The first ignition pulse is applied to the switching transistor so as to switch the collector voltage so that high voltge ignition pulse is produced in the ignition coil. The second igniton pulse is applied to the ignition-noise masking signal generator to produce an ignitionnoise masking signal.

Title: Single stage track seek method and lens assembly control circuit
Inventor: ABATE CHARLES
IPC: G11B7/085
Filed: 1989-09-25
Granted: 1999-04-15
Abstract: A seek method for disk drive is described. In the seek method of the present invention, the tracking servo loop remains in a track positioning mode throughout the entire seek process. By effectively varying the reference position of the head with respect to track center under a predetermined profile, the track positioning mode is utilized to produce a pseudo-continous movement across the disk surface. In essence, the servo track following loop attempts to mainta position relative to a local track center as dictated by profile information supplied by a microprocessor. The system of the present invention is an open loop in the sense that no attempt is made to loop information about deviation from the predefined profile back to the microprocessor. Local positioning, however, remains closed loop at all times so that the system is always within the predicted track and arrives directly on target.

Abstract: 본 발명은 전기부품수용공간과, 상기 공간의 적어도 2개의 대향면을 따라 평행하게 배열된 복수의 접점을 가진 전기부품용 소켓이다. 
     각 접점은 가압된 상태에서 전기부품수용공간에 수용된 전기부품의 접점과 접촉되는 접촉아암부와, 상기 접촉아암에 대해 접촉력을 부여하도록 접촉아암부를 안쪽으로 가압하는 만곡스프링부를 가진다. 
     소켓은 또한 접점열을 따라 수직으로 회동가능하게 지지된 회동레버, 회동레버의 일단에 형성되고 회동레버를 상하로 조작시키도록된 조작부, 및 그 타단에 형성되고 접점에 외향력을 작용시키도록된 작용부를 가진다. 회동레버가 조작부에 의해 하향으로 회동되면, 작용부는 스프링부의 탄성에 대항해서 접점의 접촉아암부를 외부로 변위시켜서, 접촉아암부가 전기부품의 접점으로부터 분리되도록 한다.

Title: Method of fabricating a capacitor for semiconductor device
Inventor: KWON KWANG-HO
IPC: H01L27/108

Abstract: depositing a first polysilicon(9) , in which the impurity ions are implanted, on a silicon substrate(8); forming a residual film(10) by reactive ion etching of the first polysilicon(9); inserting a halide in a reactive chamber and applying RF power to the chamber to form a gas plasma; converting the residual film to a SiCxHyFz film by exposing it to the gas plasma; rapidly heat treating a SiCxHyFz film to form a SiC film(11) on the polysilicon(9); removing a carbon layer(12) remained on the SiC film(11) in the rapid heat treatment process; depositing an insulation film(13) on the SiC film(11); depositing a second polysilicon(14) on the insulation film(13) to form an upper electrode; defining a capacitor region using a photosensitive film(15); and removing the photosensitive film after etching the portion except capacitor region. Formation of the SiC film having a high dielectric efficiency provides a higher capacitance.
